Study ObjectivePlatelets play a pivotal role in metastasis of tumor cells. The aim of this study is to explore the effects of sevoflurane and isoflurane on platelets activation of patients undergoing lung cancer surgery, and the effects of sevoflurane and isoflurane on platelets-induced invasion of lung cancer cells.DesignProspective and randomized study, and in vitro experiment.SettingUniversity-affiliated teaching hospital and laboratory.PatientsForty-six patients scheduled for lung cancer radical surgery.InterventionsPatients were randomized to two groups of 23 patients each and were received sevoflurane (group SEV) or isoflurane (group ISO) during surgery, respectively. In vitro, lung cancer cells were treated with platelets in the presence or absence anesthetics.MeasurementsPlatelets activation were determined by detecting glycoproteinIIb/IIIa (GPIIb/IIIa), CD62P, and platelets aggregation rate (PAR) pre-, intra-, and postoperatively. Invasion ability of lung cancer cells were evaluated by Transwell assay.ResultsThe levels of GPIIb/IIIa, CD62P, and PAR were reduced markedly in group SEV during perioperative period compared with group ISO. In vitro, activated platelets contributed profoundly to the invasive ability of lung cancer cells. Sevoflurane, but not isoflurane, inhibited platelets-induced invasion of lung cancer cells. Furthermore, sevoflurane suppressed the platelets activity in vitro.ConclusionSevoflurane attenuates platelets activation of patients undergoing lung cancer surgery. In vitro, sevoflurane suppresses platelets-induced invasion of lung cancer cells via decreasing platelets activity.Copyright © 2016 Elsevier Inc. All rights reserved.
